To all whom it moy concern,.- E V Be il known that I, JOHN SMITH, of the city and county of Philadelphia, State of Penn sylvania, vhave invented a new and useful Improvement in Candy-Dropping Machines, which improvement is fully set forth in the following specification.

My invention relates to candy-dropping machinee; and it consists of a novelconstrnction ro of' devices whereby the operation of the machine is rendered automatic and provision is |nade..for restoring-tbc parte to their normal positions for the next successive operation.

'lo the above ends my invention consists of novel means for intermittently forcing the candy material through the apertures in the bottom of the box in which said material is contained. It also consists o'f a' bed having means for automatically raising and lowering the same, said bed being also provided with channels for the reception of sprocket-chains and having spring-pressed pl ungers adjacent thereto for locking the trays to thebed.

It also consistsof a novel construction of sprocket `chains and v'wheels therefor, said' chains being interniittentlypropelled and carryin g plates therein which receive the candy. It also consists of novel means for inter- It further consists of novel details of construction, all as will be hereinafter set forth.

The operation is as follows, attention-being called to theA fact thatl will first describe' the I raising" andlo'wering of theplungerin the receptacle, the adjustment of the plunger and the raising and lowerintr ofthe bed, .andthe insertion and' removal f .the trays, it .of course' beingsJ understood thatthe'partsoperate in unison and in proper sequencezxFirst,

4edtoeont'ain o il, so` that the parts :will he with respect to the plunger, material having a 'been placed in the receptacle, power isiapplied to the main shaft 1', which gives motion through the gears 2,3, 5, and- 6to theshafts 4 and 8. These latter'carry the cams l() and 11, which in their revolution force-down the headsl l2, and` this depresses the rods, 13,

which" carry 'the' cross-head 16, which supports the vplunger 24, which is thus depressed roo in the receptacle 17, which forces a'predetermined portion of the .material therefromA through `the perforations 20, and when the cams 10 and l l en terthe pockets 72 thesprings heads 12,- cross-head,16, and `,the plungerv 24.

23 .force up the rods. 13. andfwith them' the .j

Io5 As now some el thematerial Vhas been forced from the receptacle it Airnecessary to adjust I the plunger with respect to the cross-head 16, A and this is accomplished in the` following. manner: As'the shaft 8 revolves it carries; with ii the crank-aun 35, which carries with it tbe rod 33, the latter causingthe arlu.29 to IIO be raised and lowered. f Thiscausesthe pawl' 30 to engage with the ratchet-wheel 31 at the proper time andlrevolve the shaft 28,V this turning the gear 27, which meshesfwiththe beveled gear- 26 and'turns the same, whereby the feed-screw is depressed, carrying with it-f Y the plunger 24 to an extent equal tothe space -occupied by the material which has been forced from the receptacle, it beingnoticed that this movement takes place afterthe. material ha'sleft the receptacle. f

' In order to raise the bed 46with the tray 67 thereon to receive the. materiai forced through the openingsA 20, the following operation takes place: As theshaft 8 revolves it 4fr nrnsthe cam 71, which strikes the arm 36 l rbd elevatesthe same. This carries up the secured, the end off'which is thus raised,l

forcin'gu p the post 42, which carries the bed 46, which is also raised with the tray 67 theresgf ceived the material, will.

sure, since the collar which receives the material, it being seen that this takes place as the plunger descends, The spring 44 allows for any exoessiof'presi5 is looseonthe said post 42 and is connected to the lever 404 The parts descend io their soon as the cam releases the arm 36.

In order to remove a tray 6T-after -itlhas rethe edge of ,the same is engaged bythe shouwl normal.. positions asV be noticed that" der 68 on one of. the links of thechain and anintermittent movement is imparted4 to the chain in the following manner:

As the gear@ revolves rthe crank-pin 58 engages with the arm 59 and depresses the same.

with the gear 63 turns the same. The payvl n thereon engages with the ratchet 66,A which turns the shaft 64, to which the sprocket# wheel lis secured, which is turned thereby,

thus moving forward-pthe chain and the' tray dotted lines to the' l Thismoves theV quadrant 6l, the teeth of whieh-.engaging` clel i7 and ready to receive the next supply, k of material, the operati-ng parts returning to their normal positions when the pin has passed or released the arm 5i), the pawl riding over the teeth of the ratchet, and thusV not moving the chain, it being noticed that this action takes place after the plunger 24 has been elevated and the bed 4G returned to its normal position, the chain noi being moved, as.

the recesses et? permit movement of the bed without disturbing the said chains.

In order to lock the trays to the bed as the latter is'clevatcd, I provide the plunger 52 with the nose 57 thereon, which latter engages with the said tray and pinches the same between il. and the bed. The nose 57 and plunger are carried up by the bed, and when the lai i er descends the spring 55, which has been com pressed, returns the said plunger and nose to thci r normal position, the stop which I provide for thc samel preventing the plunger and nose i'rom descending too far and forming a space between said nose 57 and bed 46, in which space. the tray is adapted to enter.

I have provided various means to adj ust all the working parts, it being evident that all tho movements take place in suchrotation and in `tuch relation to each other that the machine is automatic in its action.

Il, will of course be evident that slight changes may be made by those skilled in the art which will come within the scope of my invention, and I do not therefore desire to be limited in every instance o the exact construction heroin shown and described.

llaviug thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
